Current research show that female passengers have a lower capacity for injury compared with males when subjected to the same level of harm. Additionally, safety protection for rearseat passengers is less effective than for those in the front, posing a greater safety risk for smaller individuals in the rear seats during collisions. This study proposes a corresponding injury optimization solution. Firstly, a collision analysis model was constructed based on the CNACP frontal collision conditions. The reliability of the model was verified through a comparison with data from a frontal collision test, which involved a 100% overlap with a rigid barrier using the Hybrid III 5th female dummy. Subsequently, optimization designs were conducted based on benchmark results, comparing and analyzing the impact of different optimization configurations on passenger safety. Finally, an optimization plan was determined, which included adding collision locking tongues, configuring linear pretensioners, increasing seat stiffness, and adjusting seat belt force limit values. In comparison to the original design, the overall score for the rearseat female dummy during the collision process improved by 84%. According to the CNCAP star rating criteria, the score for the rearseat female dummy now exceeds 94%, indicating an excellent performance and validating the effectiveness of the optimization. The methods in this study provide a reference for research on injury optimization for smallsized rearseat dummies.
